Greetings. It's a type of Scale. You can spray Neem or Horticultural Oil (a contact insecticide) directly on the bugs. Then as a preventative, try a systemic insecticide (which enters all parts of the plant from within). See page 7 of the Insecticide Fact sheet here:  https://brunswick.ces.ncsu.edu/2018/02/making-sense-of-pesticides/
